Chemical and radiological sample results
MS0380009 , Toomsuba Water Association
43 of the 73 analytes this system has been tested for have been detected at least once, across 404 samples on record.
An analyte is counted here if any result on record measured it, so this covers the whole history and not the samples listed below.
Across all 404 samples on record, detections range from September 29, 2003 to July 8, 2026. These figures cover the whole record.
What counts as a non-detect is defined in the help: Less than Indicator. This system’s violations.
What has been detected, ever
Every analyte measured above its reporting level at any point in this system’s record, most often detected first. This is not limited to the samples listed below.

The most recent samples, result by result
The table below lists 261–270 of 404 samples, newest first — collected January 24, 2012 to April 5, 2012. The summary above covers all 404.
26 results from the 10 samples listed here: 1 detected, 23 not detected, 2 with no result recorded. Across the whole record it is 427 of 2,499. A sample is analysed for many analytes at once, so one sample appears on as many rows as it had results.
